Considering a move to bioplastics? Consider the experience of John Deere, which is now in the eighth year of a program to use soybean and corn feedstocks that was not originally driven for green reasons. The biomaterials are used in combine panels, backhoe loader hoods, and tractor hoods. Greg McCunnn, who runs the project, says the materials must be cost competitive and must be a performance drop-in for petroleum-based plastics. Needless to say, significant supply chain work was involved, and included funding from the United Soybean Board. Ashland Specialty Chemicals developed polyester resins that include soy and corn feedstocks, while processors Ashley Industrial Molding and Budd (currently Continental Structural Plastics) worked on the molding side. There were also issues related to painting and mold release.
And it amounts to more than a hill of beans: each combine made with the compound uses 1.1 bushels of soybeans and 0.5 bushels of corn.
Inspired by the hooks a parasitic worm uses to penetrate its host's intestines, the Karp Lab has invented a flexible adhesive patch covered with microneedles that adheres well to wet, soft tissues, but doesn't cause damage when removed.
Researchers at the Missouri University of Science & Technology have designed a new nanoscale material that can transmit light faster than the 186,000 miles per second it usually takes to travel through air.
It has often been said that as California goes, so goes the nation. This spring, the state's wind power is setting energy generation records and solar energy generation is expected to rise sharply during the second half of 2013.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
